IMPROVEMENT IN WIOOLv-WA'SI-IING MACHINES.

Specification forming part of Letters Patent No. 173,222, dated February 8, 1876 application led.

' v January 20, 1876.

'To all whom it may concern:

chine Box, for cleansing woolwaste, rags,

paper-stock, or any kind of dirty wooleu stock used in woolen-mills, also for cleansing cotton-waste, ofwhich the following is a specifi-v cation: i

The object ofmy invention is to increase.

the quantity of' Work with vless labor and expense and scouring material.

My invention consists of a tank or box built of Wood or iron, with an .inside box built of metal of a circular term, perforated with holes, which can be dumped either by hand or power, said inside tank or box beingfulcrumed'upon one edge of the outer one. l

In the drawings, Figure l`is a plan view as seen from above; Fig. 2, a longitudinal Section through the lines a: w ot' Fig. l; Fig. 3, a side view when the inside tank is raised when dumping the wool.

Aisthe outer tank; B, theinside perforated one, lot'metal or any suitable material.. a is the pinion for-operating the rack b, perma nently attached to the inner tank at d. e is a friction-roller. f is the attachment of the inner tank to the outer. y. is the crank for ro-l tating the pinion c, and h the shaft connecting to a similar pinion upon the opposite side. A

duplicate of rack b is upon the opposite side, andnot shown. kis apulleyiu the ceilingofthe room; l, the attachment of the weight-cord m. Inside the circular box of metal there -is a space for sediment which settles from the stock in process of scouring. When the'wool is dulnped, the sediment remains in the bot tom of thel tank or box. In this way the liquor is prevented from being stirred tup, and

as a consequence is kept ina purer form. v Inv all manufacturing' c0ncerns,. the Wool, after it is scoured, is thrown-out witha fork. It generally takes from one-half Ato three-quartersof an h our tothrow out short-stapled wool, and even then it is ldifficult tojget out all of the wool, as it slips through the fo1'k,and a good deal of it remains in the box. Then, too, the wool remaining becomes very much damaged by remaining. It not only becomes discolored, but loses, in ay great degree, the strength of its ber.

With my invention the wool can be en- My invention saves the sediment and dirti in the tank from beiugthrown onto the door,

thus making a neater job, `and leaving no dirt or water about,;outside of the tank.

Connected with the metal box, and on each side vof the same, there are circular racks with pinions, by' means of -which the box is raised or dumped. These are so graduated as to be counterbalanced by a weight, W, suspended I from theceiling, and passingover a pulley, c, inthe inside tank, so thataboy can dump the wool.

They can be worked from either side, and.

stopped at any point'in the process of dump` ing, so that the liquor can'be drained into the tank, thus saving the liquor, and preventing its waste. As shown, the box is raised by means oi' a crank; but it can be soarranged as to be worked-either by hand or power.

The base on which the tank or box stands represents the loor. It is made thick; otherwise it could not be worked. On the metal box there is a stud, on which there is a sheave for attaching a cable `for comiterbalancing. The box may be built in a square l or circular form.

Another advantage of my invention' is, that it does not bead the wool. rI he machine works clear. The water or liquor is received from4v I one side, and discharged from the other side through any openingdesired.

. I am aware that an inner tank to be raised is not new, but vI knor of' none combined with a dumping device.

Having described 'my invention, I claim as follows `An -inner 'perforated tank combined with an outer tank or box, 'upon which it is fulcrnmed Y at one end or side, and a curved rack with j pinion-wheel and crank, for elevating the in-4 ner'tank to dump the wool or other article be-l ing cleansed, all arrangedsubstantially as de#V scribed.
